DRAIN-TILE AND SEWER-OUTLET PROTECTOR.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed. anuary 17. 1906. Serial No. 296,557.

To all whom it may concern:

Be it known that I, JOHN A. TENOLD, a citizen-of the United States, residing at N orthwood, county of l Vorth, State of Iowa, have invented a certain new and useful Improvement in Drain-Tile and Sewer-Outlet Protectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in drain-tile and sewer-outlet protectors, and has for its object to provide a device which will at all times and under all conditions allow an unobstructed flow of water and a free circulation of air therethrough and at the same time effectually exclude animals, vermin, sand, dirt, and other foreign substances.

It also has for its object to provide a draintile and sewer-outlet protector which will not rot away and which is simple, inexpensive, and durable in construction and which can be easily and readily adjusted to the outlet or mouth of a drain-tile or sewer and be held securely in place and which cannot be washed away.

It consists in the several features and combination of features, as hereinafter more fully described and claimed.

In the drawings which illustrate my invention, Figure 1 is a top plan view; Fig. 2, a side elevation; Fig. 3, a central vertical section on the line a; :r of Fig. 1; Fig. 4, an end elevation with the gate closed, and Fig. 5 an end eleva tion with the gate open.

Referring to the drawings, in which like numerals of reference denote like parts in all the several views, 1 represents my improved draintile and sewer-outlet protector, which comprises a tube or cylinder 2, substantially round in cross-section at the inner end 3 and square at the mouth or outer end 4:, and said end 4 is cut at an angle of preferably fortyfive degrees, as at 5, and each side edge is turned outward laterally from a point 6, below the upper edge of the tube 2, to form a flange 7, while the bottom edge 8 is turned over downwardly onto itself to strengthen said bottom edge. Said tube 2 is larger-in diameter at the inner end than at the outer end for the purpose of allowing the ends of draintiles of different sizes to be inserted and retained therein.

A band 8 is secured over the outer portion of the tube 2 by rivets 9, as shown, or by any other suitable means, for the purpose of strengthening and reinforcing said end, the outer edges of said band abutting against the lateral flanges 7, as shown at 6, which assists in keeping the band in place, and said band also projects over and beyond the top wall 9 of the tube for the purpose of forming a stop 10 for the gate, to be hereinafter described.

The tube 2 is provided with a gate 11, seated on flanges 7 and lower edge 8 thereof and at an angle of forty-five degrees, said gate having perforations 12. therethrough which may be of any desired shape or size and of any number. The lower corners of the gate are rounded, as shown at 13, to prevent any liability of their being caught on anything, and thereby keep the gate from openmg.

The upper portion of the gate 11 is cut inward to form shoulders 14, and the upper edge is turned over on itself to form a tube 15, and 16 is a removable pin on which the gateis pivoted or hung and which is inserted through holes in the sides of the band 8 and through the tube 15. By having a removable pin for the pivot of the gate said gate can be readily removed and replaced by another one if for any reason it is found desirable, and by hanging the gate at an angle of forty-five degrees and having a stop for the same it cannot open too far or be left open, as it will be kept closed automatically by its own weight.

Tile and sewer-outlet protectors as a general rule are washed away when there is a full flow of water or when they are flooded by an undue amount of water caused by hard rains, &c., or when the least obstruction gets into the tile, and to obviate this I fasten my tube 2 securely to the ground by means of two wires 17, which may be of any desired length, and each of which is attached at one end to hooks 18 on the side of the tube 2, while the opposite ends of said wires are provided with anchor-plates 19 and are embedded in the ground.

I preferably construct my invention of galvanized iron; but it may be made of any suitable material.

It is very desirable that the gate should not open to a greater extent than is absolutely necessary, and therefore I make the mouth or outer end of the drain-tile and sewer protector square, which spreads the water passing therethrough out in a sheet, and the same volume of water will not rise as high in a tube with a square end as it will in a tube of a round IIO or other shaped end, and therefore with the square end the gate is not opened as wide as it is with a tube with a round end.

In use an ordinary flow of water will pass through the perforations of the gate and not I open the same; but just as soon as the vol- I ume of water increases and produces an unusual flow of water it will open the gate until it has passed through, when the gate will automatically close on account of its being arranged at an angle of forty-five degrees in relation to the end of the tube and assume its normal position.

I do not desire to be understood as limiting myself to the specific details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement on the adaptation of the device to various condi-. tions of use without departing from the spirit and scope of my invention and improvements. 1 therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms of the following claims.

What 1 claim is- 1. A drain-tile and sewer-outlet protector comprising a tube square at one end and round at the opposite end, a band embracing said squared end and a gate pivoted to said band, substantially as described.

2. A drain-tile and sewer-outlet protector designed to be appliedto the outlet end of one of a plurality of drain-tiles and comprising a tube, a band embracing the outer end of said tube and having its front edge terminating at a point at the rear of the mouth of the same, and a gate pivoted at the outer end of said tube and designed to have its upward movement limited by abutting against said band, substantially as described.

3. A drain-tile and sewer-outlet protector comprising a tube round at one end and square at the opposite end and cut off at an angle of substantially forty-five degrees, a pivoted gate, and a band embracing said squared end which projects beyond the end of said tube at the top to form a stop to limit the upward movement of said gate, substantially as described.

4. A drain-tile and sewer-outlet protector comprising a tube having a gate, means for holding said tube comprising hooks attached to said tube, and wires to attach to said hooks and provided with plates designed to be embedded in the ground, substantially as described.

5. A drain-tile and sewer-outlet protector designed to be applied to the outlet end of oneof a plurality of drain-tiles and comprising a tube having flanges extending from its side edges, a band embracing the outer end of said tube and abutting against said flanges, a perforated gate pivoted to said band and designed to have its upward movement limited by abutting against said band, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

JOHN A. TENOLD.
